Limestone Binder In Iron Ore Pellets

Iron ore pelletizing systems - liming

Iron Ore Pellets are formed from beneficiated or run of mine iron fines. The iron is usually ground to a very fine level and mixed with limestone or dolomite as a fluxing agent and bentonite or organic binders as a binding agent.

effectof limestone binder in iron ore pellets

The term iron ore pellets refers to the thermally agglomerated substance formed by heating a variable mixture of iron ore, limestone, olivine, bentonite, dolomite and miscellaneous iron bearing materials in the range of 1250 deg C to 1350 deg C. Iron ore pellets are normally produced in two types of grades namely DRI grade and BF grade.

Effect of adding limestone on the metallurgical properties ...

Aug 10, 2015 · In this study, the effect of adding limestone on the metallurgical properties (reducibility, swelling, cracking, softening temperature, Low-Temperature Disintegration, Cold Crushing Strength) of acid iron ore pellets was investigated using a comprehensive set of metallurgical laboratory tests.

Pelletizing - Wikipedia

Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces.They typically contain 64%-72% Fe and various additional material adjusting the stone composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.. The process of pelletizing combines mixing of ...

Taconite - Wikipedia

To process taconite, the ore is ground into a fine powder, the magnetite is separated from the gangue by strong magnets, and the powdered iron concentrate is combined with a binder such as bentonite clay and limestone as a flux. As a last step, it is rolled into pellets about 10 millimeters in diameter that contain about 65% iron.

Use of Boron Compounds as Binders in Iron Ore Pelletization

Use of Boron Compounds as Binders in Iron Ore Pelletization The Open Mineral Processing Journal, 2010, Volume 3 27 3.1. Function of Binders Binders are used to improve pellet properties as listed below: • Promoting and facilitating - balling of iron ores in pellet-izing drum or disc; • The improvement of green, dry, pre-heated and fired

Iron Ore Pelletizing Process: An Overview | IntechOpen

Bentonite, an inorganic binder, has been the main binder used in the iron ore pelletizing process since the beginning of pellet production in the 1950s. Bentonite promotes the formation of ceramic bridges between particles, which can minimize the number of pellets that collapse during firing.

Pelletization - an overview | ScienceDirect Topics

Jan 01, 2012 · The selection of an appropriate binder type and dosage is of critical importance in producing good quality pellets at a reasonable price. Binders accomplish two very important functions in iron ore pelletization: The binder makes the moist ore plastic, so that it will nucleate seeds that grow at a controlled rate into well-formed pellets.
